transforming Number to String not working

[Bleck]

i have a small problem and no matter what i do i am not able to transform specific doubles into strings i dont know if the number is too long or maybe is something to do with too many decimal numbers but when i try to change it into a string to add to another document it breaks any one knows a way to fix this??

Hi @Bleck

This should be achievable by using the -Round Double- node instead of the Number to String:

Change the Output format to “Standard String”

Hope that helps,
